Reassessment of the dipole in the distribution of quasars on the sky
We investigate claims of an anomalously large amplitude of the dipole in the distribution of quasars on the sky. Two main issues indicate that the systematic uncertainties in the derived quasar-density dipole are underestimated. Firstly, the spatial distribution of the quasars is not a pure dipole, possessing low-order multipoles of …
